AXLE FUR RAILROAD-CARS.

'0 all whom it may concern:

Be it known that I, .linnzs I (loom. a citizen of the United States,residing at Fayettei'ille, in the county of Washington, State ofArkansas, have invented certain new and useful Improvements in Axles forRailroad-Cars; and I do hereby declare the following to be a full.clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention is directed to im ro'vements in axles for railroad cars,and as for its object to construct an axle of this character so that thewheels may rotate independently of each other.

A further object is to provide an axle of this type which is strong,light in comparison to those in general use, thus reducing the cost to aminimum.

\Vith these and other objects in view, this invention resides in thenovel features of construction, formations, combinations and arranements of parts to behereinafter more lly described, claimed. andillustrated in the accompanying drawing, in which Figure 1 is anelevation of the device. Fig. 2 is a longitudinal sectional view throughthe axle and wheel. Fig. 3 is a sectional view on line 3-3 of Fig. 1.Fig. 4 is a similar view on line 4-4 of Fig. 1.

The axle consists of sections 1 and 2, the section 1 being provided witha tapered spindle 3 which fits within a similar shaped bore 4 formed inthe section 2. The sections 1 and Q are formed integral with flangedwheels 5 and 6, respectively, each of which have formed upon their outerfaces journals 7. The wheel 5 is provided upon its inner surface with anannular flange 111 the outer rovided with threads 9 which are engaged ythe threads 10 formed upon the inner surface of the flange 11 of thecircular cap 12, said cap being provided with a central aperture 13which receives one end of the section 2. The section 2 is provided atits larger end with an annular shoulder 14 which is held in place by theSpecification of Letters Patent.

cap 12 thus preventing separation of the sections 1 and 2. Pivotallyconnected to the inner surface of the wheel 5 is a spring pressed pawl15, one end of which engages the ratchet teeth HS formed upon the outerface of the annular flange 11, thus preventing accidental rotation ofthe cap, which might occur when the movement of the axle has beenreversed. From this construction it will be seen that an axle has beenpro vided which is so constructed that one wheel may rotate independentof the other when traveling on a curve.

The wheel is provided with a duct 17, and through which oil may pass tolubricate the axle.

To place the cap .12 upon the section 2 two-part mold is placedtherearound and molten metal poured therein and hardens,

after which the mold is removed, thus leaving said cap slidablyconnected to the section 2.

What is claimed is 1 An axle of the class described consisting ofsections, wheels carried by each section, one of said sections beingprovided with a tapered IJUI'P," spindle t'ormcdwith the other sectionand adapted to fit in said bore, said spindle being tapered, an annularflange formed upon the inner face of the wheel carried by the secondnamed section, an annular shoulder carried by the first named scctioinacircular cap having a flange adapted to engage the annular flangecarried by the wheel, an aperture formed in the cap for receiving oneend of the first named section so that said cap will engage the annularshoulder formed upon the first named section to prevent separation ofsaid sections, and means carried by one of the wheels for engaging thecap to prevent accidental rotation thereof.

In testimony whereof,I afiix my signature, in presence of two witnesses.
